Hello brothers. Those of us that have been around here long enough and have done our reading, know that the amount of oxytocin produced by women during sex diminishes as her sexual partner count increases. This reduces her ability to create a stable pair bond with a mate over time.

My question is how does this affect a woman, who has lots of sex with the same man, over time? Does it diminish with time as well? I've been curious about this and if it has any effects on the newness and excitement in the context of an LTR.

Your expertise is appreciated!
